I am positive after looking at my A-frame (and my previous PUP) that PUPs and A-frames do not have factory wiring diagrams or factory wiring harnesses. The man/woman assembling the unit wires it up with some crimp-on wire nuts and a spool or two of wire at hand. I can safely say that after seeing the total lack of color coding or wire sizing behind the converter/distribution panel. After viewing how it was done, I am amazed that everything electrical actually works on my unit!
I have yet to see or hear of a PUP or A-frame that has a master disconnect switch as it comes from the factory. Owners sometimes install a battery disconnect after purchase as a convenience (I have on the present unit). And PUPs/A-frames all have a switch to disconnect electrical stuff in the roof when the roof is lowered - although it's possible it could have been omitted or mis-wired during construction. So I think you were given a line by the person at Rockwood you talked to - or that person didn't know any better.
3) Turns out one of my fuses is blown and if the 120v is used I guess it does not run through that fuse. The fuse seems to deal with many of the 12v systems including the battery charging system as my voltage at the battery increased when I changed the fuse also. The power converter in my system is totally different than what my user manual describes, but seems like it was the stock unit...
PUPs and A-frames generally use a combination converter/distribution panel, made by WFCO. If you pop the front cover off, you will see 1-4 AC circuit breakers (like your home electrical panel) on one side, and a stack of fuses for 12V DC circuits on the other side (smaller version of the fuse panel in your car). In RVs, 120V AC uses circuit breakers, 12V DC uses fuses at the panel.
It is worth the time to figure out which breaker and which fuse controls what and LABEL the panel (again, just like your house). There are additional fuses that are not in the panel, such as in-line fuses at individual pieces of gear (like the stereo), and an in-line 12V circuit breaker on the chassis near the battery.
Hope this helps
